1. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
2. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
3. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
4. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
5. Matter: Physical and Chemical Properties
How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.
6. States of Matter and Chemical Versus Physical Changes to Matter
The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
7. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
8. Physical Change: Definition, Properties & Examples
Changes occur to substances every day. Some of them are natural, and some are caused by human beings. In this lesson, you will learn about physical changes and understand examples of these changes.
9. Retention Factor in Chromatography: Definition & Formula
This lesson explores chromatography in the laboratory as a way to analyze mixtures. The equation for the retention factor is defined as a means to identify the components of a mixture.
10. Solute Concentration: Definition & Overview
In this lesson, you will learn the definition of a solute concentration. Also, an example will be included to assist with your learning of the science behind a solute concentration.
11. What Is Distillation? - Definition, Process & Apparatus
Explore distillation, the chemist's most useful method for separating substances dissolved in liquids. We cover the cycle of vaporization, cooling, and condensation that is the basis for the process. You will also learn what laboratory apparatus you need to perform the procedures involved.
12. Antoine Lavoisier: Atomic Theory & Contribution
In this lesson, we will learn how Antoine Lavoisier changed the way chemistry is studied. By collaborating with other scientists and putting their discoveries together, he helped develop a new understanding of the fundamental elements of chemistry.
13. Antoine Lavoisier: Biography, Facts & Quotes
Known as the 'Father of Modern Chemistry,' Antoine Lavoisier was a French scientist who made great discoveries in the field of chemistry. This lesson looks at the personal life of this great man, from his early education to his death.
